We will all be dead and gone before ever reaching that point. The best you could hope for would be a survivalist contingent sent out before we kill ourselves off. And, they would not be what I call a “normal” citizen grouping.

I did see on a Mars documentary that we now have the technology to ‘terraform’ (or whatever you call it) the Martian atmosphere to one that would be suitable for humans, but it would take some 50 years to do so. Basically the same thing they were doing on the planet LV-426 in the film Aliens. The only thing stopping us from doing so is the trillions of dollars someone would have to be willing to throw away spend on the project.

Humans won’t be living on Mars for probably at least…500 years, would be my guess. If we’re even still a viable species at that point, of course.

Not for a hell of a long time, is my guess. Currently, we haven’t been further than the moon, and getting that done today is still an ordeal. We have satellites and devices that can go really far yeah, but no current technology, so far, that allows us to colonize any planet, or moons. It also doesn’t help that society’s current advent is making money, not colonization. This might happen faster were our energies put into it. How much funding does space exploration get these days, anyway?
